Peanut high-yield skills: How wide is the ridge? How far is the plant spacing?

Peanut is the main food crop in China. It is planted in large quantities throughout the country. However, the output of peanuts planted by many farmers is not satisfactory. Today, the cherry sister teaches you how to make high-yield peanuts. How wide is the peanut planting? How far is the plant spacing? Come and see with Cherry Little Girl!

The double-row dense planting mode of peanuts has a wide distance between large ridges, and the distance between the two rows is dense and has the advantages of ventilation and moisturization. It has obvious effect on increasing peanut disease resistance and increasing peanut yield, and increasing yield compared with local conventional planting mode. %about.

1, peanut high-yield skills implementation method

  1.1 Peanut planting site selection: Select sandy soil arable land with flat terrain, loose and moderate fertility, and plant it on low-lying and easy-to-grain soil.

  1.2 Peanut high-yield method : Choose the local main plant variety Huayu 34. Planting 2 rows of ridges with a distance of 80cm, a small row spacing of 30cm, a hole spacing of 12 to 14cm, and an acreage of 20,000 to 22,000 plants increased by 2,000 to 4,000 plants compared with conventional ridges.

1.3 Peanut high-yield test design : 200 acres of double ridge cultivation, and 10 acres of conventional planting mode as no control.

1.4 Peanut planting field management : Before the planting in the demonstration site, 40 kg of compound fertilizer (NPK: 17-17-17) was applied as a base fertilizer per acre in the middle of April. On May 15th, the machine was planted, the seeding amount was 14~15kg/667m2, the hole distance was 6cm~7cm, and the peanut seed was seeded with the seeding agent “chlorpyrifos” at a ratio of 500g/667m2. The herbicide acetochlor + herb was used for 5 days after sowing. Dry soil sealing. Artificial weeding was carried out 3 times during the whole period of birth to prevent the occurrence of aphids in the late July. The whole field was sprayed with 40% dimethoate 2 times to control aphids. From mid-July to late September, 70% methyl thiophanate 1000 times solution, carbendazim and chlorothalonil were sprayed 5 times to prevent leaf spot disease, and trace elements such as boron, molybdenum, potassium and calcium were added. Harvest in time for harvest.

2, peanut high-yield skills analysis

Huayu 34 cultivated in the double-row dense planting mode, the plant height and branch number were not significantly different from the conventional cultivation mode. The number of single plants was 17.3, which was 3.4 less than the conventional planting, and the fruit weight per plant was 19.6 g. Less 0.6g, but the number of harvested plants increased the population density by 3878 plants, which increased the yield of mu, and the yield per mu reached 409.3kg, which increased the yield by 65.8kg compared with the conventional cultivation yield of 343.5kg, and the yield increased by 19.2%. The effect of double-row dense planting cultivation is more obvious than that of conventional cultivation.

Large ridge double-row dense planting mode Because 4 rows can be planted on 160cm wide land, the local conventional planting mode can only grow 3 rows on 160cm wide land. The number of peanut plants on the land of one acre land is 1.3 times of the conventional planting mode, the ventilation between the large ridges is good, the distance between the double rows is relatively close, and the loss of soil moisture is effectively prevented, so that the peanuts are in a good growth state throughout the growth period to achieve higher yield.

Therefore, the large-row double-row dense planting cultivation mode is one of the feasible measures to increase the peanut yield in our district and increase the economic benefits of the rural areas. Cherry Xiaomei hopes that this article will help everyone. I want to know more about planting techniques. Welcome to Huinong.com!
